This is awfully complicated. Would it be possible to just get the kernel 
to give us the right ID back, perhaps by adding a new socket option?

For that matter, I guess the same goes for the first part of the 
series—if we could get a way to get a SOCK_RAW + IPPROTO_ICMP socket, 
presumably one where the kernel filters out anything unsafe, that'd be a 
lot nicer than fixing things up in Wine...
